No. Across our 13 million inspection records, 387.301(b) has placed only 1 vehicle out of service in its entire enforcement history—a 0.4% OOS rate. This code is not OOS-eligible by regulation. For context, the national average OOS rate across all FMCSR codes is 31.4%, so this violation is significantly less likely to result in a roadside removal.
387.301(b) ranks #1178 out of 3,036 FMCSR codes by citation volume. We have recorded 230 all-time citations in our database. To put this in perspective, peer codes in the General/Admin category rack up tens of thousands of citations each—for example, 390.21TB2-DOT has 74,663 citations. This code is relatively rare on the road.
First, request a copy of the inspection report from the officer or your carrier. Review the specific finding and understand what documentation or condition triggered the citation. Second, consult your carrier's safety manager or your company's compliance department—they can help you determine if the citation is accurate or whether a DataQs challenge is warranted. Third, do not ignore it; even low-OOS violations become part of your CSA safety profile and can affect insurance rates.
No, relative to peer codes. 387.301(b) has a 0.4% OOS rate, while similar General/Admin violations like 390.19B2-BIENNIAL have 0.2% and others like 390.21(a) have 0.0%. All of these are far below the 31.4% national average OOS rate. This is an administrative citation, not an acute safety violation, and enforcement is infrequent—zero citations in the last 12 months.
Knowles Trucking LLC (USDOT 1246064) has the most citations on record with 3 findings. Major Transportation Services Inc and TMT Trucking LLC each have 2. Most other carriers in our database have received just 1 citation. With only 230 all-time citations spread across hundreds of carriers, this is not a pattern violation affecting any particular carrier segment.
Yes. DataQs (Crash and Roadside Data Quality Monitoring system) allows drivers and carriers to challenge inspection findings within 90 days of citation. If the officer misapplied the regulation or the documentation supports your compliance, submit a formal challenge with evidence. The FMCSA will review and correct your record if warranted. Consult your safety manager or a compliance specialist to prepare your case.
Low urgency from an OOS standpoint, but do not delay compliance. We recorded zero citations for this code in the last 90 days and zero in the last 12 months, indicating rare enforcement. However, the citation still appears on your inspection history and CSA profile. Address the underlying condition or documentation gap promptly to avoid repeat findings and maintain a clean record with insurers and brokers.
Freightliners account for 17 of the 230 all-time citations, followed by Volvo with 8 and Freightliner with 7. However, this likely reflects their prevalence in the fleet, not a defect-specific issue. The violation is administrative in nature, so vehicle type is less relevant than driver or carrier compliance with documentation or registration requirements.
